Semiconductor device

Abstract

In order to reduce the chip size of a semiconductor device as well as to separate noises between at least two types of pads having different functions, at least one Vcc and at least one Vss are provided on opposite edges of a package (101) so that output pins or I/O pins are arranged therebetween and input pins are arranged outside the same. Non-connected excess pins (NC) are arranged on upper and lower boundaries, for omitting wires and reducing the chip size.

What is claimed is: 
     
       1. A semiconductor device comprising: a chip and a package for storing the same; and   a plurality of external connection pins being provided on two opposite edges of said package,   said external connection pins including: power supply pins being formed on said two opposite edges of said package respectively for supplying power to said chip,   ground pins being formed on said two opposite edges of said package respectively for connecting said chip to the ground,   input/output address/data pins being formed on said two opposite edges of said package outside said power supply pins and ground pins, and   excess pins being not connected to the exterior,     said excess pins being arranged between said power supply pins and said ground pins on said two opposite edges of said package respectively.
